Well I see one problem in your equation right off---you can't charge a battery by running it to another car with jumper cables for 20 minutes. Not even close. Not even close to close. So you weren't diagnosing things using a "good" battery.
 
So why don't you fully charge (slow charge) the battery overnight and then see how the car's computer likes that.

well, this exact thing happened again!
2006 mustang with pony package. my wife just had it washed 2 days earlier and an "intermittent" electrical issue occured yesterday!
The first time this happened car was under warranty and they replaced a "pillar" gasket seal to prevent water entering cabin area and trickeling down pillar to inside passanger kickplate (where this electrical connection that I found was showing moisture corrosion on terminals )-I have pictures of proof that i submitted to FORD-
 
Second time 1 1/2 years later,after heavy rain, happened again. Car was out of warranty. Ford said sorry, not covered. I cleaned terminal dry and worked for some time until yesterday.
 
This time, an Intermittent electrical issue on her car had a complete electical system shutdown and then it came back on! She had car washed 2 days earlier and was driving in a snowstorm on I-80 after work. Had car towed in town to investigate issue.
 
will keep you posted if same problem. ">

#170 of 197 06 Mustang electric drain while key is off by krudawg

Apr 04, 2011 (7:57 pm)

I am the original owner of a 2006 Stang w/pony pkg autoTrans. It has the Shaker 500 and all the available options. I also had the dealer install a LoJack system. At the 30K service they called and said the battery needs replacing as well as the alternator - even though it was starting up and charging fine with no problems. So it was done under warranty and at 52k miles I'm having dead battery issues (if car is parked more than 2 days. Autozone check battery and said it tested OK. So I have a friend put ammeter on the car after it has been shut off and and initially showed 1.XXX amps and after about 6 or 7 minutes it dropped to 0.30 and stayed there. I started pulling fuses one-at-a-time and when I pulled fuse #66 the load dropped to .12 and when I put the fuse back in it went back up to .30 so I pulled the fuse out and placed it in the "extra slot" I then started the car back up (V6) and check to make sure all the usual stuff worked and it did including the radio and powered seat. Here's the kicker - the owners manual states fuse position #66 is not used. I read a lot of stuff that the problem is with the Shaker 500 so I had a shop install a JVC KD R810. The drain on the battery remained at .12 with the new radio and everything works except I still am getting a dead battery after 2 days. I spoke with the Ford Service guy and he told me that according to his stuff that fuse #66 is not used. He told me to bring it in and they would open the fuse box and trace the wire at fuse #66. I told him that I didnt have $80/hr to have their tech's do what I could do but that as a dealer THEY should know what is on that fuse! So anyway, anybody happen to know why Im getting a battery drain that kills the battery in 2 days ?

Ok, My 2 yr old Motorcraft battery which was replaced by the dealer under warranty finally failed today. I purchased a new battery and installed it today and I hope it solves my problem but I still have a battery drain of 110ma which is about double the draw that most new cars may have. I will keep this thread updated as time moves forward

You should be fine with only 110ma draw.

Did you find out how to fix this? I am having the same problems on a 1995, i've narrowed it down to the green wire off the top of the altenator, but dont know where it leads too???
 
Any help?

Hey guys. I got 2006 Mustang V6. My "CHECK CHARGING SYSTEM" warning keep coming on. Changed the battery, alternator and checked alternator fuse and wires and it's all fine. Does anyone knows what the problem could be?

Only thing left are the battery cables and terminals. It's also possible the replacement alternator is bad or the wrong model.
